Application tiled July 2S, 2.9M), SerialNo. 574,331.

To all whom it ymuy concern.'

Be it known that l, JOSEPH Si. Poor-rn, a citizen ol the United States ef America, and resident of Kew Qrleune, in the perish of Orleans und State of Louisiane, have invented certain new and ueel'ul improvenients in Valve-Starter Alarme, of which 'the followingf is a Specification.

My invention rela'Iv te a Valve Starter valarm applicable especially to globe, gate, straightway Vertical, Straightivay horizontal, back pressure Valves.

The Scope of invention is set forth in the claims hereinafter annexed.

In the drawing, the single ligure is a horizontal section ot' the complete construe-tiem The essential elements composing the device which involves my conception are a` valve chamber l having a hose .2, at the left side and a packing box at the other Side, a valve 4 in said chamber hy which the no1-t5 may be closed when seid Valve is pre i` upon the Seat G, a valve Stein T extending through the packing hex and having a thread 8 extending through a Support i), by which the valve iS propelled on turning` the handle l0, on the stem 7, a. second packn ing box 11, for the valve chamber on the bons 2, for an extension l2 of the stem to pass through into a compartment i3, a third packing hox 14- at the other end of the crun pertinent 'from the boss 2, for the extension to pass through, a 'circuit closer at the outer end of said extension and movable hack and forth with'the Valve stern, and a thumb Screw Contact 1G, with a lock nut l?, in thev path of the circuit closer for closing the circuitto ground at the binding;l post 18, the terminal wires entering' by the tulle 19. There is another contact 20, which may he used for an insulated circuit instead of or' in conjunction with the ground at i8, and which is also in the path et the circuit closer.

rlhe operation is simple. By turningl the is closed by the circuit closer l' thereby preventing tampering with the relire. @n closing` the Valve the circuit is aggein'infokeu. To adjust the contacte (l and Q0 correctly, the Valve should he opened wide, und then the contacts Screwed against 'the circuit. closer l5, and locked in that position by the lock nuts 1T and l? The Valve inav then be cloned. lVhen it is opened again, the contacts are included in the alarm circuit.

l claim as niy invent-ion l. In combination, a valve stein, a 'valve carried thereby, au extension of said stein, ay packing hoi; through which said extension passes, an electric circuit closer caried hy said extension, and an electric Contact in the path of said circuit closer, by Which an electric circuit is closed when the valve is opened. v

2. In combination, a Valve chamber, a valve therein, a stein for the valve, a packing;` box through which said Stern passes, i1. thread on Said stein, a Support through which passes. Said thread, an extension from the Stein, a Second packing,` box. through which said extension pfisses, a Second. cha1nher 13 screwed. to the Valve cheinher for receivineT Said extension, a third packing box through which said extension passes :from Said chamber 13, a` circuit closer carried hy said extension, and an electric contactin the path of Said circuit closer hy which. an elec-k JSEPH A.
